T all 'whom it may concern:

Y Be it lmown that I, HARRISON M. SEAG- ERs, a citizen of the United States, and resident of Geneva, `in the county of Ontario and State of New York, have invented certain new and useful Improvements in Em-y of the operator; toprovide a convertible press readily adaptable for `either hot or cold embossing; to provide a press readily adapted for use with dies supported face upward over the lower press head or face down under the upper press head; to provide improved means for'raising and loweringthe lower press head; to provide improved means for supporting and guiding the shiftable head of the press; and to provide improved means -for kadjusting the lower press head lifting means.

Other highly important objects of the invention are to provide an improved antifriction cam lift mechanism for presses of the type disclosed in patents` to Pollock, No.

1,163,740 and No. 1,497,872 and to Seagers, et al. No. 1,497,795; to provide improved means for controlling the movements of the antifriction rolling elements and thrust plates and the shiftable head in presses of this type; to provide an improved raising and lowering mechanism of this type so constructed as to substantially increase the throw thereof, and consequently increase the normal distance between the upper and lower press heads, without any `substantial increase in the effect required to actuate the press; to simplify and improve the work supporting means; and to provide a press of the type disclosed in said patents which may readily be used forcold or hot embossing.

' To the foregoing and other ends, which will hereinafter appear, the invention consists in the improved constructions of de- @59 vices, the arrangements of parts, and comF binations of elements, set forth in the following description and particularly pointed out in the appended claims.

The main frame or press body is cast in one piece and is of general rectangular form, the walls of the metal casting being thick and strong. The bottom wall 1 is provided with a front Aflange 2 and a rear flange 3 to afford a broad bearing for the press body on a work bench or'other. support to which the press'body is rigidly-held by screws or bolts 4t passing through slots 5 in said flanges. The frameor body is preferably relatively wide from side to side and relatively narrow from front to rear, as shown. Vertical side walls 6 and 7 connect the bottom wall 1 with the top wall 8 what. @saintes the mam fixed member of a ,two-part non-shiftable upper press head, the lower face 9 of said wall 8 being flat and disposed in a horizontal plane. TheA inner faces of the side' walls are parallel with each other and lie in vertical planes. rlhe top face of the bottom wall 1 has a raised fiat horizontal central portionv 10 connected by downwardly and outwardly inclined portions 11 with" two lower fiat horizontal end portions 12. j l

The lower or vertically shiftable press headv member 13, together with the parts carried thereby, is supported on a pair of independently adj ustable leveling and supporting blocks 14 through the medium of' the antifriction caniA mechanism by which said head member 13 is shifted, as more fully hereinafter set forth. Each of the blocks 14 has a fiat top face whileV its bottom face is parallel with the top face from the out'erend of the block to a point about midway the ends of the block and then extends upwardly and inwardly in an inclined plane to-the inner end of the block. The junction of the two inclined bottom face portions of the block forms a fulcrum portion 15 extending fore and aft of the press which engages the adjacent inclined face portion 11 ofthe bottom wall 1 of the frame andy i's'adaptedto rock thereon and slide up and down face 11. A split ovateleaf spring` 16A is confined under compression between the reduced inner ends of blocks 14 and normally urges the blocks toward the side-walls 6 and 7 of the press body against the rounded inner ends of adjusting screws 17 which-pass through threaded holes in the side walls of the press body. y

Blocks 1l are preferably formed of cast iron and constitute adjustable and' rockable supporting wedges seated within the main frame of the press which is also preferably formed of cast iron. Head member-13l is a flat, horizontally disposed oblong block pref# erably formed of hard steel. The ends of member 13 slidably engage and are guided by the vertical inner faces of walls 6Y and 7 and its front and rear edges are engaged and guided in all positions of the shi'ftable head member by the slightly inwardly turned upper edges of sheet steel face plates 18 which are detachably held to the-press body by screws 1 9 and close the lower portion of the open front and rear sides of the rectangular body or main frame.

The head member 13 is shifted up and down by impartingrotary motion to armember 22 and horizontal reciprocating motion to a lpair of thrust members 2O between which member 22 rotates. These' three members are preferably formed as shown and geared together, and member' 22 preferably ha's` a vertical movement in a plane through its axis, but the construction ofthe lifting mechanism maybe widely varied. In the present application claims are' made to generic features of the invention' as well as claims to the particular embodiment thereof shown in the drawings. Certain modified constructions of presses will be shown and particularly claimed in other applications.

The member 22 shown comprises a steel cam shaft having two parallel fiat faces 22L and 22b tangential to two reduced cylindrical bearing portions 22c and 22d, two cam faces 22e and 22I eccentric to the bearing portions and connecting the flat faces, and a projecting endportion 22g adapted to t inthe socket 23 of a metallic hand lever 243. Face 22e rises slightly from its junction with face 22')` to its junction with' face 22a' while' face 22f rises slightly from its junction with face 22a to its junction with face' 22". For convenience in manufacture part 22g isI formed at the same time and the same shape as' the main working section of the cam shaft, and lever socket 23 shaped toy fit over part 22g to which it may be locked byv a set screw'ja's shown in Fig. 6. The parts of the lifting mechanism are normally in' the positions shown in Figs. 1, 2,- 3, 5 and 6, being arrested in this position by eng-agement of a stop lug 25 on lever 2l with end wall or stop abutmentv 26 at one endv of a segmental recess 27 formed in a boss 28 on the outer face of wall 7 of'the press body. Stop 25 moves in this recess when lever 211 is actuated. Bearing portions 22c and 22d correspond in diameter with the width' ofvertic'ally elongated slots', ways, or bearings 29 and 30 in walls 6' and 7 and slide up and down androtate therein'. The fiat faces of the cam shaft arespaced apart a distance'equal to the diameter' of the bearing portions so that theshaft may be passed through slot 30' in assembling the ress.

The' thrust members 20' are indntical in form and interchangeable', each comprising a relatively thick steel plate oblong in plan, one face being fiat throughout and the other face Ibeing flat and parallel with'the first mentioned face from the outer end" to a line adjacent and parallel with the inner end of the plate and then inclin'in'gl toward the first mentioned face and the inner end of the plate. The' inner portions of the plates are thus reduced in thickness by cut'- t'ing away one fa'ce of each plate near one end, and in the construction shown` said face is cut away to formA an inclined plane surface. The' plates 2O are arranged" norm'ally with the inclined faces of the'` reduced portions thereof engaging` the fiat faces of the cam shaft so that the" sh'alft is supported by the lower plate and the upper plate isI supported by' the' shaftwith the Hat faces of the shaft extending downwardly and rearwardly in" planesl parafllel with the inclined faces of the reduced inner portions' of the thrust plates.

ooL

Antifriction rolling elements are arranged over the upper thrust plate and below the lower thrust plate and preferably, as shown, steel non-traveling bearing plates 21 are in-` terposed between the lower set of rolling elements and the wedge blocks and between the upper set of rolling elements and the bottom face of head member 13. Plates 21 are fiat and relatively thin and are oblong in plan View. As shown thev rolling elements comprise two sets of steel rollers 31 extending transversely of the press, the ends of the rollers in each set being confined in longitudinal slots 32 in a pair of sheet steel retainer bars 33. Bars 33`are disposed in vertical planes and extend fore and aft `of the'press opposite and close to the side edges of plates 2O and 21.

The upper pair of retainer bars extend over the cam shaft and the lower pair of bars extend under said shaft, said barsbeing reversible and interchangeable and having one longitudinal edge thereof cut away near one end and the reduced end portion thus formed bent laterally at a right angle to the main body port-ion to form a lug, hook or projection 34 engaging behind the outer edge of the adjacent thrust plate 2() but free from the adjacent bearing plate 21. The outer edges of plates 20 are preferably out awa-y to form recesses 35 in which the projections 34 seat when the parts are in normal position.

A positive mechanical driving connection is preferably provided between each traveling member 20 and the rotary and vertically sliding member 22 of the head shifting mechanism. As shown these connections are toothed gear connections and comprise two rows of short teeth 36 on each thrust plate 20 extending fore and aft of the press meshing with two circumferential rows of recesses or tooth sockets 37 formed in the main working portion of the cam shaft. Teeth 36 are provided on both the inclined and horizontal portions of the adjacent faces of the two plates 20 and sockets 37 are provided in both the fiat and eccentric faces of the shaft 22, the rows ofteeth and sockets being of suiiicient length to maintain the driving connections throughout the range of movement of the parts. The positive drive thus provided-insures prompt and uniform movement of plates 20, provides for positively restoring the roller bearings toy the same point after each press operation, and

assists in preventing accidental displacement of the traveling elements of the liftin mechanism. Y

It will be observed that the head member 13 and devices thereon are supported by the lifting mechanism just described. It is highly desirable to prevent tilting of the head member 13 during shifting movements thereof or when pressure is applied to one end of the work carriage, as such motion of the head 13 may cause derangement of the work or displacement of some part of the operating mechanism. To this end said head member is guided as above described by the side walls 6 and 7 and face plates 1S and is further supported by a combined balancing or steadying and return mechanism which will now be described. A pair of sheet steel rectangular balancing plates 33 are hung on the reduced portions 22c and 22d of the shaft 22, said plates being interchangeable and provided with large circular apertures 39 through which the eccentric portion of the cam shaft may be passed. These plates are confined between the adjacent side walls of the press body and the shoulders formed at the junctions of the cylindrical bearing portions of shaft 22 with the main central eccentric portion of the shaft and thus prevent accidental endwise motion of the shaft. The plates are of such size and soV located that they also prevent endwise motion of rollers 31 and cooperate with plates 20 and21 to hold the retainer barson the ends of the rollers. The top edges of the plates engage under the side portions of head member 13 when the parts are in normal position and the vertical front and rear edges of the plates slidably engage the face plates 18, thus forming a steady and firm support for member 13 when said member is in its normal lowermost position. To further steady and guide the parts, insure prompt and easy return of the parts to normal position, and to' limit the extent of upward motion of member 13, a pair of steel stop bars 40 are provided. These bars 40 extend fore and aft of the press body along the inner faces of walls 6 and 7 and are'constantlyheld pressed up against the lower flat face of the top wall or fixed head member 8 by coil springs 41. Each block issnpported near its front and rear ends at each side of the verticalV plane of the cam shaft by two of the springs 41, the upper ends of the springs being seated in sockets 42 in the bar and the ylower ends of the springs beingfseated in sockets 43 in the member 13. Lateral motion of the springs and bars is prevented by guide pins or posts 44 seated loosely in sockets 43 and passing up through thecoils of the springs part way into the sockets 42. Springs 41 are normally under compression and tend to constantly press member 13 downward, the pressure being exerted adj acent each of the four corners of head member 13. The parts are kept under constant and even pressure in such manner as to insure easy and prompt action and prevent accidental displacement thereof.y

The press is preferably provided witha fore and aft shiftable work support or traveling carriage 45, which in the construction shown is several times as long as the distance betweenthe front and rear edges of head members' 8v and 13 and; is detachably and slidably held to member 13 by a guidi n ing-` and retaining rod 46to slide back and forth on the top face of member 13' in a horizontal plane. The carriage comprises a long flat sheet -steel plate having upstanding vertical side fianges 45a disposed in planes y just inside the stop bars 40, and also having through member 13 and has a forward head 46a abutting against the front faceof flange 4'5" and is provided with a* transverse bore 461J near its other end sodisposed that a removable fastening or cotter pin 48 passed PL' i.

therethrough ,abuts against the rear face of flange 45. The end iianges are stiflened where the rod passes therethrough by stamping out parts of the bed of the carriage and y turning them down toform short depending` flanges 49 close to and parallel with the adjacent end flanges. These flanges49 Iare also adapted to act as stops and engage' the front and rear edges of the member 13 above the y top edges of the face plates to limit fore and aft movements of the carriage and keep any part thereof from being jammed against the face plates 18. A handle 50 isv affixed to flange 45h, said handle' preferably comprising a' metal rod bent to Uishape and having reduced ends passing throught the flange and headed down against the rear face of the flange as shown at 50". The carriage has a continuous plane surface adapted to support long pieces of work or both long pieces ot work and long dies or die forms, or a series of short pieces of work or long series of both short work pieces and short dies or die forms and by shifting the carriage longitudinally between successive squeezing operations of the press it will be evident that successive areas of work maybe presented between the head members, which are relatively short from front to rear as above de# scribed.

m12 e e To adapt the press for either hot or cold embossing with the die or die form supported on either the stationary upper head or the shiftable lower head. two flat detachable and interchangeable head members are provided, the member 51 comprising av solid steel block or cold` embossing head member and the member 52 comprising a hot embossing head-` member consisting of a flat metal block having an electricv heating element 53y set in the obverse face thereof in the well known manner andcovered by a metal face plate 52, the reverse face of said block 52 having acovering 52b of heat insulating material l thereon.

The combined thickness of partsV 52,v 52EL andl 52b of the hot' head member is equal tothe thickness of the cold head member, and: head member 51 is provided with' a conoidal socket 54 in both the fore and aft side edges thereof near its reverse face midway between theA front and' rear edges of the member,` while, head member 52 is provided with a similarly located pair of conoidal` sockets 55. Either of the head members 51-52 may be firmly secured to the fined head member 8 with the reverse face thereof pressed firmly against the bot# tom face 9 of said member 8 by. screwing the conoidal ends of screws 56 intol the sockets in the side edges of the detachable member.` The screws 56 are threaded in apertures 57 in the side walls at such a. level with regard to the sockets that they willv cam the detachable head member firinly against member 8 (see Fig. 1)' so that the detachable member may be held firmly in place by only two screws.` Members 51 and 52 are of such width that their side edges terminate inside the flanges 45a of the carriage which may move up and down between the blocks and the sides of either head member that may be heldk to member 8. The nonthreadedinner portions of the Shanks' of screws 56 passv loosely through apertures 58 in stop bars 40 and are located above the limit of upward movement of the upper edges of fianges and the carriage 45.

Gold embossing.

In Figs. 1 to 4 th'e cold embossing head member 51 is shown attached toV fixed head member 8 to adapt the press for use in embossing by the cold process. In some classes of work it is preferred to work with dies supported in inverted position above the material toy be acted upon. This method of embossing may be performed by placing the material on the carriage and (1) placing the inverted die or dies on the material and forcing both dies and material up toward member 51, or (2) cementing the inverted die or diesY to the under face of head member 51 and forcing the inaterial up toward the dieV and member 51:,l or where very thick dies or material are used, by removing member 51 and either cementing the die to the bottoml face 9 of head member 8 or placi ing the die face down on the'work on the carriage. It is usually preferable, however, to work with dies supported face up on the lowenhead with the material to be embossed laid' over the dies. This is especially true when using the press tomake' embossed display cards or the like of the character referred to in the patents mentioned above. For this class of work the die or die form may be simply placed face'up on the carriage 45 and the material placed on the die or (2) the die or die' forinmay be ce# f shown in Figs. 10 and 11.

' mented to the carriage face up or may be cemented or otherwise secured to or in a chase or holderplaced on the carriage. The carriage is well adapted for use with a chase or set up card of the character disclosed in the application ofv Lublintz and Trokie, Serial No. 747,806, filed November 4, 1924.

Hot embossing.

To adapt the press for embossing by the hot process, head member 51 is removed and the electrically heated head member 52 is (1) attached to head member 8 by Vthe screws 56 01?(2) placed non thecarriage as Studs or short projections 59 kare preferably pressed inward from the body of flanges 45a of the carriage and are adapted to spring into sockets 55 in member 52 to assist in detachably holding the member to the carriage. When member 52 is held against member 8 the press is adapted for use with inverted dies which may be cemented to face 52a 'of the heated head or may be placed on the material on the carriage and shifted up against the heated head. lVhen the member 52 is attached to the carriage, as shown in Figs. 10 and 11, the dies or die form may be simply placed on or may be cemented to the face plate 52a of the member with' the faces of the dies uppermost and the material placed over the dies and squeezed against face 9 of head member-'8. As it is, as above set forth, usually preferable to employ dies arranged face up and as it is frequently desired to employ long dies or forms, member 52 is preferably made several times as long as ythe distance between the front and rear faces of the press body, as shown, so as to cover all or substantially all of the flat surface of the carriage that is shiftable forwardly of the two head members 8 and 13. A suitable flexible electric conductor cable or cord 60 is provided for connecting heater 53 with a source of current, the cable being provided with attachment plugs of ordinary form and being of sufficient lengthV to permit free movement of the heated head with the carriage.

It will be observed from the foregoing description that a simple and powerful press of compact construction is provided capable of use in a wide variety of ways for embossing materials, the press shown with a face area of `about nine inches by four inches for heads 3 and 13 being capable of developing a pressure of approxiinatelyeight tons with applicationaof comparatively slight effort to the hand lever 24. It will be evident that whilerthe press is particularly suitable 'for use as an embossing press it is not limited to such use and,` while it is highly advantageous `especially in embossing work to employ the long 8 a fixed head is provided comprising two detachably connected sections, and that when members 52 is attached to the carriage a vertically shiftable head is provided comprising two sections one of which is detachable and is lalso horizontally shiftable relatively to the other and of substantially greater length from front to rear of the press.`

By adjusting blocks 14 uniformly toward or from each other the member 13 and carriage and the entire lifting mechanism may be bodily elevated to vary the normal distance between the squeezing heads. Shim plates may be interposed between member 13 and the adjacent bearing plate or between blocks 14 and the adjacent bearing plate, or at both these points, if desired to effect very substantial change in the normal level of member 13. As the several plates andV antifriction rollers between member k13 and blocks 14 are relatively long and may vary in thickness slightly from end to end, the blocks 14 may be adjusted as shown in Fig. 9 or in the opposite direction to compensate for such variation and maintain member 13 perfectly level. By constructing the blocks 14 as above described it will be noted that when adjusted as above set forth they tilt so that the top faces of both blocks lie in the same plane (see Fig. 9), which is a' highly desirable and novel feature of the adjust-v able supporting means.

lVith the parts as shown in Fig. 3, forward rocking of the hand lever for about one-fourth of its throw will turn the cam shaft until the flat faces inclined slightly forward and downward and the lowerparts of the eccentric faces begin to roll on the horizontal parts of the toothed faces of the horizontal moving thrust plates,"thus causing a quick substantial upward sliding movement of. the cam shaft in its bearings and a greater upward movement of the head member 13, The press is preferably adjusted so that at this point the heads are just close enough together to begin'squeezing the dies against `the work.' The continued forward and downward movement of the lever to the position shown in Fig. 4 brings the top face of head 13 up against the stop bars 40 whereupon upward movement of head 13 is posi- 'tively arrested to'fprevent the dies being forced too far into the work. This final liftof head' 13 is relatively slightiand due to the rolling of the slightly eccentric faces of the cam shaft between the plates. When head 13 engages bars 40 stop aceQaroiflug 25 ,is slightly above .the bottom V.wall Qot' recess 27 in boss .28. If rvpower is still .exerted on'lever 2.4 after head '13 strikesibars 40 stop Vface .25a will engage .wall 26 and positively stop swinging .motion .of .the lever beforeinjurious strain is imposed upon the lifting mechanism. Vhen the lever 24 is swung back to normal position plates 2O will be driven positively back to the positions shown in VFig and will-.positively drive the rollers 131 fback to their starting position through .the medium of lugs '3:4 on the retainers.

'Byreducing the innerrends offthethrust plates a substantial increase infthrow vis vobtained with parts otra-given proportion over presses constructed asshown iinthe patents above referredto without anundesirableincrease in the throw :of =the hand lever Land without increasing the effort required to voperate vthe press. This is highly important as owing to the somewhat limited clearance in the patented pressestlie work .or die :forms were sometimes derangedin sliding the same between the press'heads, especially when the operator workedirapidly.
